SPECIFICATION forming part of Letters Patent No. 404,095, dated May 28, 1889.

Application filed July 21, 1888. Serial No. 280,583.

(No model.)

To all whom t may concern.-

Be it known that I, JOSEPH J. LADD, of Callao, Peru, South America, have invented a new and Improved ReplacingFrog, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which- Figure l is a side elevation of one part of my improved replacing-frog. Fig. 2 is aplan view of the same, and Fig. 3 is an end elevation. Fig. 4 is a side elevation of another part of the frog. Fig. 5 is avplan view of the same, and Fig. 6 is an end elevation.

Similar letters of reference indicate corresponding parts in all the views.

The object of my invention is to construct a light, portable frog for replacing derailed locomotives and cars, to be entirely supported by the rails, and by which gravity will be made available for shifting the car or locomotive laterally.

My invention consists in the construction and arrangement of parts, as will be hereinafter fully described, and specifically pointed out in the claims.

To the head of the rail A is fitted a clamp, B, the body of which is formed of a U -shaped bar, a, provided at one side of the rail with an offset, b, for receiving the footof the rail, the said oset portion being furnished with a lip, c, adapted to pass under the edge of the foot of the rail. The opposite end of the U-shaped bar a is bored and threaded te receive the clamping-screw C.

In the central part of the Ushaped bar aI is inserted a stud, el, (shown in dotted lines in Fig. 1,) which is provided with a collar, e', received in a recess formed in the top of the bar, the end of the said stud (l within the U-shaped bar a being riveted.

The inclined bar D, which is designed to rest at its lower end upon a tie or other suitable support, is provided with a forked npper end, f, each branch of which is bored to receive the stud d, so as to permit of using the said bar D upon either the right or left hand side of the track. The bar D is angled near the fork f to bring its upper end parallel with the head of the rail, and its lower part is beveled, while its extremity is bent downwardly, forming a retainingedge for engagement with a tie or any suitable support.

The device to be attached to the other rail is shown in Figs. 4, 5, and G. The clamp F is composed of the part h, parts i' i', formed integrally with the cross-bar c2, and the part i", adapted to engage the foot of the rail A', the part 7L being provided with avslot, j, for receiving one half of the foot of the rail, and the parts t' c' being adapted to reach over the other half, as shown. Upon each part i is formed an ear, 7c, for receiving the bolt Z, upon which is placed the eye m, provided with the shank n, extending through a hole in the part 7i and held in place by a transverse pin, o. The part i" is provided with an arm, j', which extends toward the rail A on the part h, and in which is inserted a stud, d', corresponding with the stud d of the other part of the device. VVashei-s d2 are placed between the ears lc and the eye m.

The replacing-bar D corresponds to the bar D, and is provided with a forked end, f. The forked end f is furnished with apertures for receiving the stud d', as in the other case. The bar D is made much wider than the bar D, and is provided with a heavy sheet-iron covering, p, which exten ds from the fork to the beveled extremity thereof, and is bent down over the edges of the bar, as shown in Fig. 1i, and rests on the ties between the fork and lower end of the bar D.

lVhen a car or locomotive is derailed, the clamp B is secured to the rail by the screw C, and the inclined bar D is secured in place means of the stud d, the beveled end of the bar D being placed as near the derailed wheel as possible. In like manner the clamp F is secured to the rail and the bar D is placed in the position of use, with its beveled end as near as possible to the wheel to be replaced. The bar D is arranged above the head of the rail, and the bar D is arranged below the head of the rail, the said bar D being placed upon theinner side, while the bar D is placed upon the outside of the track. With this arrangement the wheel between the track-rails is elevated by being forced up the inclined bar D, and the wheel outside of the track is elevated by being forced up the barD. A locomotive having only two wheels off the track may replace itself; but where all its wheels are derailed the truck will have to be enrailed by jacking; then place a jack under the fer- IOO ward axle, at equal distance between the wheels, and raise that pair of wheels suinciently to place the point of the frogs underneath. The springs will allow of doing this without raising the back end of the engine. Having done this, take out the jack, and it will be fo und that the engine will easily mount the rail. When the derailed wheels are run upon the bars D D the axle of the locomotive or car will be inclined andgravity Will tend to carry the wheel over toward the rail A', so that very little effort will be Vrequired to replace the locomotive or car after it has been lifted by the inclined bars D D.

Having thus described my invention, I claim as new andrdesire to secu re by Letters Patentl. In a replacing-frog, the clamp B, formed of a n-shaped bano., havingonelegprovided at its lower endwith an offset, b, for receiving the base of the rail, said offset portion having an inwardly-projecting lip, c, to pass under the rail, and the bolt C, extending through the opposite leg of the clamp, substantially as set forth.

2. In a. replacing-frog, the clamp F, consisting in the horizontal piece 7L to pass under the rail and slotted to receive one side of its base, the cross-bar i2, resting on piece h and having the part z" to engage the opposite side of the base of the rail, and the parts z' z', each having an apertured ear, la, the shank n, passing downward through a hole in the part h, and having an eye, m, in line with the earapertures, and the bolt Z, passing through said ears and eye.

3. In a replacing-frog, the combination of the clamp B, adapted to engage the head of the rail, the clamp F, arranged to engage the foot of the rail, and the forked inclined bars D D arranged to be supported and held in position of use by the said clamps, substantially as specified,
